This GIF Shows Where New Yorkers Live By Age And Sex

The turquoise dots represent male residents of New York City, and
the magenta dots represent females. The GIF goes through ages 0
to 85+ showing the distribution of New York's population broken
down by age and gender, based on data from the US Census Bureau.

What's really interesting about the maps is how much they reflect
New York City's culture. Ages 0-15 give an idea of where parents
are raising their children, while the 15-19 age range begins to
show clusters of prisons and colleges — Morningside Heights, for
instance, is bright pink thanks to Columbia University and
Barnard College, while Rikers Island is filled with green dots.

You can also watch the map change drastically as people get
older, and couples move out to the suburbs. The maps also become
progressively more pink due to the fact that men tend to die
sooner than women.
